:an edge view of the sash. Fig. 4 is a c'orresponding or inner side-view of the movable connection-piece ot' the sasl. Fig. 5 is a. vertical sect-ion of the sashes and window-frame and The purpose ot'V my invention is to enable a sash to be easily removed from the windowframe in order that the panes of the sashv may be easily washed or. cleansed.

I n the drawings, A denotes a. window-frame madein theordinarymanner,andhaving within it two sashes, B O, the frame being so constructed as to allow ot' either of the sasbes beingmoved vertically within it. 4

In carrying out my invention I make the sash to which it is to be applied of a width somewhat less than the distance betweenv the bottoms of its window-frame grooves diminished by the depth of one oi them. In consequence of thisl construct one side bar, a, of the.

sash C 0f a width less than that of the other,

viz.,b, and 'with the said sash and inthe groove c, which is neigt adjacent to the lesser bar, a,l l employ a connection bar or slide,D,to which A I attach one of the cords of the sashb-alancing This connection bar or slide D may have a sash to better advantage than it would be were there no such iiange or rib to the bar D. rI he `said'bar I), placed within the groove c, has the sash against itand its iange, and there should be bolts h h applied to the sash and catchest i applied to the bar D, for connecting the bar and sash together, such bolts being so arranged that they may-be moved by a person when on the inner side of the sash. 4By withdrawing the bolts from their catches the Sash and the connection-bar will be soseparated as to enable a person to readily remove the sash from vthewindow-frame andthe bar D.r

I would remark that in general only the lower sash of awindow-frame need be provided with my invention, for it is that sash which is the most difficult to clean on -the outside surface of its glass, on account of the necessity which existsot' raising such sash in order to get access to the outside surface of its panes. As the lower sash while beingraised will double or lap on` the upper sash, access to thcvouter cult, if notimpossible, to be obtained.'

What I claim as 'my invention isl 1. The combinationand arrangement of the bar l) and its fastening bolts and-catches, or
